Product details
Overview
74LVC16244ADGV-Q1J from Nexperia is an automotive-grade 16-bit non-inverting 3-state buffer/line driver in TVSOP48 package, operating from 1.2 V to 3.6 V supply, with 5 V tolerant inputs/outputs, IOFF partial power-down protection, and Schmitt-trigger inputs for noise immunity. It supports mixed-voltage interfacing between 3.3 V logic and legacy 5 V systems in body control modules.
For engineers reviewing the 74LVC16244ADGV-Q1J datasheet, 74LVC16244ADGV-Q1J pinout, 74LVC16244ADGV-Q1J application, or 74LVC16244ADGV-Q1J equivalent, this device is selected for automotive bus buffering where voltage translation, high-impedance isolation during sleep modes, and AEC-Q100 Grade 1 reliability are required.
Technical Context
This device implements four independent 4-bit buffer sections, each controlled by a dedicated active-low output enable (1OE–4OE), enabling granular bus segmentation. Each section features Schmitt-trigger inputs for robust handling of slow-rising signals and IOFF circuitry that disables outputs and blocks backflow current when VCC = 0 V.
The 74LVC16244ADGV-Q1J supports multibyte flow-through pinout architecture with distributed power/ground pins to minimize ground bounce and switching noise. Its bus-hold functionality (on data inputs only) eliminates external pull-ups on unused inputs-critical for automotive ECU signal integrity in unpowered states.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 1.2 V to 3.6 V - Enables operation across low-power microcontroller I/O domains while maintaining compatibility with 3.3 V system rails. |
| Input/Output Tolerance | 5 V - Allows direct connection to 5 V legacy peripherals without level-shifting components in automotive gateway or sensor interface designs. |
| Propagation Delay (VCC = 3.3 V) | 2.2 ns typical - Supports high-speed data buffering in CAN/LIN transceiver support logic and display timing interfaces. |
| IOFF Leakage Current | ±10 μA max at VCC = 0 V - Prevents damaging back-current during partial power-down in vehicle start-stop systems. |
| ESD Protection | HBM > 2000 V, CDM > 1000 V - Meets stringent automotive board-level ESD requirements per ISO 10605. |
| Operating Temperature | −40 °C to +125 °C - Qualified per AEC-Q100 Grade 1 for under-hood and cabin ECU deployment. |
| Bus Hold Current | ±75 μA at VCC = 3.0 V - Maintains defined logic state on floating data inputs without external resistors, reducing BOM count. |
Pinout & Package
74LVC16244ADGV-Q1J uses the SOT480-1 (TVSOP48) package: 48-pin plastic thin shrink small outline package, 4.4 mm body width, 0.4 mm lead pitch, and exposed thermal pad not present. Pin layout follows standard multibyte flow-through architecture with interleaved VCC/GND for noise suppression.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1A0–1A3, 2A0–2A3, 3A0–3A3, 4A0–4A3 (Pins 47,46,44,43; 41,40,38,37; 36,35,33,32; 30,29,27,26) | Data input group A | Four independent 4-bit input banks accepting 3.3 V or 5 V logic; Schmitt-triggered for noise margin. |
| 1Y0–1Y3, 2Y0–2Y3, 3Y0–3Y3, 4Y0–4Y3 (Pins 2,3,5,6; 8,9,11,12; 13,14,16,17; 19,20,22,23) | Data output group Y | Corresponding 4-bit 3-state outputs; high-impedance when respective OE is HIGH. |
| 1OE, 2OE, 3OE, 4OE (Pins 1, 48, 25, 24) | Active-low output enable | Independent control per 4-bit section; enables selective bus isolation without global reset. |
| VCC (Pins 7, 18, 31, 42) | Supply voltage | Four dedicated VCC pins reduce IR drop and improve transient response across wide temperature range. |
| GND (Pins 4, 10, 15, 21, 28, 34, 39, 45) | Ground reference | Eight GND pins provide low-inductance return paths, minimizing ground bounce in high-speed switching. |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q100 Grade 1 qualification | Validated for −40 °C to +125 °C operation with lifetime reliability testing per automotive stress standards. |
| IOFF partial power-down | Outputs automatically enter high-Z and block reverse current when VCC is removed-essential for hot-swap and sleep-mode compliance. |
| 5 V tolerant I/O | Accepts 0–5.5 V input signals and drives 5 V loads while powered from 1.2–3.6 V, eliminating discrete level shifters. |
| Schmitt-trigger inputs | Input hysteresis ≥ 0.3 V at VCC = 3.3 V ensures clean logic transitions on noisy automotive harnesses. |
| Bus hold on data inputs | Internal weak pull-up/pull-down maintains last valid logic state on unused inputs-no external resistors needed. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar 16-bit buffer applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| 74LVCH16244ADGV-Q100 | Includes bus-hold circuitry on all data inputs; identical pinout and electrical specs otherwise. | Eliminates need for external pull-ups on unused inputs-reduces component count in space-constrained ECUs. | Select when bus-hold functionality is required and no external termination is desired. |
| SN74LVC16244ADGGR | Industrial-grade (non-automotive); same electrical specs but lacks AEC-Q100 qualification and extended temp validation. | Not qualified for automotive use; suitable only for industrial control or test equipment where Grade 1 reliability is unnecessary. | Select only for non-automotive applications requiring identical function at lower cost. |
Compared with 74LVCH16244ADGV-Q100, the -LVC variant omits bus-hold but retains full AEC-Q100 compliance; compared with SN74LVC16244ADGGR, the -Q1J version adds automotive qualification, tighter parametric limits at temperature extremes, and enhanced ESD robustness for vehicle environments.

FAQ
Is 74LVC16244ADGV-Q1J pin-compatible with 74LVCH16244ADGV-Q100?
Yes, both devices share identical SOT480-1 (TVSOP48) pinout and footprint. The only functional difference is that the LVCH variant includes bus-hold circuitry on data inputs, while the LVC version does not. No PCB redesign is needed when substituting between them, though bus-hold behavior must be verified in system-level testing.
What is the maximum output drive strength at 3.3 V supply?
At VCC = 3.3 V, the 74LVC16244ADGV-Q1J delivers ±24 mA output drive per pin (typical VOH = 2.2 V, VOL = 0.55 V). This meets the drive requirements for TTL-compatible loads and allows direct interfacing with most 5 V logic families without external buffers.
Does this device support hot insertion or live insertion into a powered backplane?
No-while IOFF protects against back-current when VCC is off, the device is not designed for hot-plug operation. Input voltage must remain within −0.5 V to +6.5 V and output voltage within −0.5 V to VCC + 0.5 V during insertion. Power sequencing per manufacturer guidelines is required.
How does the Schmitt-trigger input improve performance in automotive environments?
Schmitt-trigger inputs provide ≥ 0.3 V hysteresis at VCC = 3.3 V, rejecting electromagnetic interference and slow edge rates common in vehicle wiring harnesses. This prevents false triggering on noisy switch inputs or sensor signals, improving system reliability without requiring external RC filtering.
